Caution: Please read our safety information before attempting any testing or repairs.

Best cooling results are achieved when the air is free to circulate around items stored in the refrigerator or freezer. When items are packed closely together, the air cools the outermost items but the center items will not be thoroughly cooled. Cool air never reaches the center items and they will not be properly chilled.

May sure that air can flow over and between the shelves as well as over the items stored there. Overfilling the refrigerator or freezer will result in inefficient and inadequate cooling.

An underfilled refrigerator also will not cool as well. As items cool down, they have thermal mass; a tendency to stay cool. When the refrigerator is empty, there is little thermal mass and so it warms up quickly when the door is opened.
